Description

Fluid collection and device for transferring
The present invention relates to fluid collection and device for transferring, and especially, although not exclusively, wherein fluid is the fluid that people produces, such as urine.
Background
Urinary incontinence can coverage people widely.Especially, many stroke victim are because the local cerebral damage being caused by its apoplexy suffers urinary incontinence.After apoplexy, individual can be healthy in other respects and urinary incontinence can seriously restrict their life style, and saying nothing of is the reason that individual is awkward.
Conventionally prescribed by the individual of urinary incontinence and use attached lower limb sack.Attached lower limb sack system generally includes urinal, and this urinal is bundled to individual shank and by pipe fitting, is connected to catheter or other urine collectings of being worn by individual.Urinal has outlet, this outlet have for individual or medical worker, by it, empty sack there is cock or valve.
In many cases, outlet tap or valve are downward along individual ankle, make some individual be difficult to arrive, for example, if they are old or handicapped.In these cases, as other people of care-giver or kinsfolk must operate cock or valve to empty sack.This causes the forfeiture of the forfeiture of independence and possibility individual's dignity.
Till the application's date, the outlet tap of three types or valve are generally used on common attached lower limb sack.In these, do not have a kind of be complete leakproof and all experience between their operating period the leakage problem in certain stage.
Consideration for a particular importance of attached lower limb sack user is to know when sack need to empty.The overfill if sack becomes, urine may upwards flow back in individual and (be called as " backflow ") and make individual face the risk of severe infections so.The general result of this problem is that attached lower limb sack user is unwilling to absorb fluid, and they drink still less, to avoid filling up continually sack.This for protecting from infection, be do not have helpful.In addition, from disease, the patient of rehabilitation is tending towards being dewatered, so be unwilling to take in fluid, will hinder their rehabilitation.
Some attached lower limb sack system in addressing these problems has been described in application WO-A-03/055423 (Wills, Trevor).This system comprises attached lower limb sack, and this attached lower limb sack has for detection of the sensing mechanism of the fluid levels in sack and for the treatment of the processing mechanism of the information being received by sensing mechanism.This system also comprises signal-sending mechanism, for reporting to the police to user when fluid arrives pre-definite level, makes user can before sack becomes overfill, empty the contents of sack.In some is arranged, this system also comprises pump, and pump promotion sack empties by upper outlet, has avoided individual to be bent downwardly and to arrive the outlet tap of weight-driven or the needs of valve of sack below.
For hygienic reason, attached lower limb sack need to be changed with regular interval.For example, in order to reduce the risk of infection, still do not show too much inconvenience, common attached lower limb sack can be changed once for every seven days.
The attached lower limb sack of the electronic mechanism of utilization such as sensor, controller and pump also needs power supply to move.Considering that attached lower limb sack is designed to provide more independence and freedom to their user, is suitable such as the compact power of one or more batteries.Rechargeable battery is suitable especially.For the convenience of user, preferably, before battery need to be changed or recharge, it is electronic unit power supply that battery can continue at least for example, as single sack is being used (seven days) the long time.Yet the attached lower limb sack of common discovery use such as the standard pump of centrifugal pump produces too many electric current and powers within the period of seven days with the battery supply by single.If use the standard pump of less less current drain, do not reach so needed pumping pressure sufficiently fluid is upwards sprayed through outlet from sack.
Horizontal detection can be undertaken by motor machine mechanism, such as the floating member of the surface at fluid, and the electrical contacts at the level place of the setting in this floating member contact sack.Yet motor machine measuring mechanism is usually large and heaviness, this is less desirable in seeking as far as possible little He unremarkable attached lower limb sack.In addition, the existence of moving component has the manufacture that is associated and assembly cost and can cause the integrity problem in device.Selectable attached lower limb sack carrys out test fluid level by measuring such as the urine characteristic of resistance with sensor, to determine total volume.For example, yet form (material content and the concentration) of the urine being produced by individual exists variation widely, form (for example material content and the concentration) of the urine being produced by individual depends on a large amount of variablees, comprises individual diet absorption.Therefore, by the measurement of urine characteristic, accurately determine that volume becomes difficult, particularly in very rare urine.To this solution, be to use " level is set ", it covers just in certain scope of measured parameter, arrives the level (and so volume) of appointment to indicate." level is set " and can be changed to be applicable to different individuals and their actual conditions.Yet this is apart from measuring accurately and no matter the ideal situation that their diet is taken in is far from a guy of institute.When accurate measurement does not exist, when level that level need to empty lower than sack, false alarm can be activated, thereby may increase user, need to empty the frequency of sack and prove unnecessarily inconvenient.
Other consideration about the precision measured is the probability that the moving fluid in sack causes horizontal survey mechanism to indicate mistakenly sack to empty.This can be due to individual walking or otherwise moves and occur together with being attached to their attached lower limb sack.Apparently, the reading of mistake and false alarm subsequently will be inconvenient and irritating for user.
The object of this invention is to provide improved fluid collection and device for transferring, its improvement or overcome in the problem being associated with prior art at least some.

Of the present invention other or selectable aspect in, provide in fluid reservoir or the improved fluid detection system used of fluid reservoir.In preferred embodiments, fluid reservoir can form the part such as the portable fluid collecting device of the fluid producing for recipient of leg bag system, although improved detection system can similarly be applicable to other fluid reservoir.The characteristic of testing agency for the fluid in test fluid reservoir is provided, wherein testing agency have for measure primary importance and and the second position at described primary importance interval between the mechanism of characteristic of fluid.Testing agency also has for measuring the mechanism of the characteristic of the fluid between primary importance and the 3rd position.Distance between primary importance and the 3rd position is less than the distance between primary importance and the second position.
Provide and be configured to receive the processor mechanism from the data of testing agency and the level of the fluid in definite fluid reservoir.Processor mechanism is also configured to use corresponding to the measurement data of the characteristic of the fluid between primary importance and the 3rd position calibrates measurement data corresponding to the characteristic of the fluid between primary importance and the second position to determine the level of the fluid in fluid reservoir.
In specific example, primary importance is positioned at the office, bottom of fluid reservoir, such as being in close proximity to the outlet of reservoir.The second position is selected as at the level place of the level that equals fluid when fluid reaches the threshold value volume in reservoir (" threshold level "), higher than this level reflux and the infection probability that becomes very large.In an example, be filled with the deemed appropriate threshold level of fluid reservoir of fluid of 66% volume of the heap(ed) capacity that reaches reservoir, if avoid refluxing and infect, should not surpass this threshold level.
The characteristic of the fluid between primary importance and the second position is measured by testing agency.This can be arranged in primary importance and the second position each place electrode or such as other suitable measurement devices of emitter and receptor, carry out.Whether the measurement between primary importance and the second position should be connected to each other and be changed by fluid according to primary importance and the second position.That is, when the volume of fluid is caught it and covers primary importance and the second position, and in its two positions of covering only one or while not covering any position, should there is the measurable difference between primary importance and the second position.Yet as discussed above, measurable characteristic of fluid (particularly urine) depends on composition and the concentration of given fluid.The in the situation that of urine, except other variation, measurable resistance will depend on that individual has taken food or what has been drunk before transmitting urine.Therefore, measurable difference between urine and primary importance and the second position situation that it doesn't matter and urine and primary importance and the related situation of the second position can be small in some cases, and may sufficiently not defined to determine that urine is filled into reservoir to be enough to reach the second position reliably and repeatedly.In embodiments of the invention, the measurement between primary importance and the 3rd position is used to by calibrating to improve the degree of accuracy of determining fluid levels from the data of the measurement between primary importance and the second position.Especially, primary importance and the 3rd position are more close to interval each other than primary importance and the second position.Therefore the amount that, primary importance is connected to the 3rd needed fluid in position will be less than the amount that primary importance is connected to the needed fluid of the second position.In less distance, the measurable change between situation about fluidly connecting and the situation of connection is non-fluidly more obviously with more reliable.So people can suppose, primary importance and the second position should be for example, near the threshold level (approximately 66% of heap(ed) capacity) of expectation near mutually positioning, although yet the volume of fluid is lower than the threshold level of expectation, if but the fluid in reservoir rocks and fluidly connects this two positions, the reading that uses so close primary importance and the second position to lead to errors to surrounding.If primary importance and the 3rd position are positioned as and make it is all highly possible by being immersed in the fluid of even low volume, this is not problem for primary importance and the 3rd position so.In fact, if primary importance and the 3rd position are close to the bottom of reservoir, gravity can fluidly connect primary importance and the 3rd position being measurable by the fluid of guaranteeing even low volume so.
When measuring the characteristic of the fluid between primary importance and the 3rd position, processor mechanism can determine when attempting setting up when whether the measurement of the fluid between primary importance and the second position indicates fluid to connect (being whether the volume of the fluid in reservoir is at threshold level) with what sensitivity to operate.
Electricity or the optical characteristics of fluid can be measured by testing agency, and it can be the one or more characteristics that are selected from the non-exhaustive inventory of the resistance, electric capacity, electric resonance and the light transmission that comprise fluid.
In an example of measuring resistance, the first electrode, the second electrode and third electrode are positioned at respectively primary importance, the second position and the 3rd position, to measure between it.If fluid has high resistivity, with the fluid-phase ratio with lower resistivity, the resistance of measurement will be less so.By first measuring the resistance between the first electrode and third electrode, can determine the relative resistance of fluid.If fluid has high resistivity, when the first electrode and the second electrode are never fluidly connected the change that changes to the resistance between the first electrode and the second electrode while fluidly connecting, will be little so.Yet, the Measurement and calibration between the first electrode and third electrode the measurement between the first electrode and the second electrode, make processor mechanism can determine when more accurately that fluid connects the first electrode and the second electrode (being that fluid levels arrives the second electrode).In other words, the measurement between the first electrode and third electrode can determine that processor mechanism determines that fluid levels has arrived the size of the change between needed the first electrode of the second electrode (met or surpass pre-definite threshold level) and the second electrode.Certainly, this is not exclusive for resistance measurement and electrode.Within the scope of the invention, utilize other feature measurement of other testing agencies can utilize this layout.
Described above, the location of the second position has determined that the fluid of what volume is corresponding to threshold level.This is preferably arranged so that the backflow in leg bag system is impossiblely maybe can not occur, thereby minimizes the risk of the infection of user.In preferred embodiments, the second position orientate as make when fluid reservoir be contained in its heap(ed) capacity 55% and 75% between and preferably its heap(ed) capacity 60% and 70% between and further preferably its heap(ed) capacity 64% to 68% between fluid volume time start and fluid contact.In preferred embodiment especially, the second position is orientated as and is made to start and fluid contact when fluid reservoir is held 66% the fluid volume that equals substantially its heap(ed) capacity.
